摘要
路网交通流宏观基本图(MFD)是用于描述路网交通流宏观变量(流量、密度、速度)间的关系模型,城市路网交通流MFD的提出与发现对于城市路网交通流运行状态评价与控制具有重要的理论意义与应用价值。本文将比例-积分控制策略应用于北京望京地区路网中,并比较了不同情况下路网运行指标的差异。
The macroscopic fundamental diagram(MFD)of traffic flow in road network is used to describe the relationship between macroscopic variables(flow,density and speed)of traffic flow in road network.The proposal and discovery of urban road network traffic flow MFD have important theoretical significance and application value for the evaluation and control of traffic flow status of urban road network.In this paper,the proportional-integral control strategy was applied to the road network of Beijing Wangjing area,and the difference of road network operation indexes under different conditions was compared.
